Good question, Lou. I wish I could help. Never saw anything like it.

Sherry

Drafting tool?

Manual rhinestone setting tool? You clearly put something in the jaws and push down.

Thanks for your response.
If the springs on the sides are compressed the 2 blocks on the sides go up past the jaws, about 1/8 inch.

Might have something to do with jewerly ???
I'll try a Post there.
Thanks, Lou
PS : Sherry , what are you doing here LOL !!!

It is a tool used for clocks or maybe watches.

Here is a link that might be useful: Clocks

Thanks for the info and the Link.
You just jogged my memory.

It is close to Presto #4 in the link.

I think my wife bought this at an Auction in the late 60's,
when I was building a Grandfathers Clock.
Never had to use it.

Don't get Old, you forget things.lol !!!

Thanks to all the others too.
LOU

Too Late Lou, already old, that is how I remembered. LOL

Brother has an old Grandfather Clock the same tool in its tool box.
